Apache CloudStack vs Electros

Apache CloudStack is free, open-source software for deploying and managing networks of virtual machines as a highly available, scalable IaaS cloud platform. Organizations can use it to build public, private, or hybrid clouds. Its features include compute orchestration, network services, account management, resource accounting, a web interface, and an open API. Operators can manage clouds through a web UI, command-line tools, or REST API, with optional AWS EC2- and S3-compatible APIs. Supported hypervisors include XenServer or XCP, KVM, Hyper-V, and VMware ESXi with vSphere. Storage options include iSCSI, NFS, Ceph RBD with KVM, volume encryption, snapshots, and storage tiering. Authentication options include OAuth2 single sign-on, two-factor authentication, TOTP, SAML, and LDAP. The project says CloudStack can manage tens of thousands of physical servers across geographically distributed data centers. Long Term Support releases receive bug and security fixes for 18 months after the main release. Operators remain responsible for protections such as monitoring, host security, and defenses against DoS and brute-force attacks.

Electros is a Metacloud control plane for governing public, private, and sovereign clouds and hypervisors from one interface without replacing existing infrastructure. Teams state infrastructure requirements as cloud intents, and Electros composes governed infrastructure to meet them. It provides a GUI, CLI, and API, alongside cross-provider orchestration, centralized observability, and cost visibility. Atomosphere maps AWS, Azure, Google Cloud, and more than 10 other cloud providers across more than 235 data centers, with real-time cloud cost comparison. Atomosquare connects VMware, Proxmox, Hyper-V, and private clouds. Electros communicates with infrastructure through Elemento’s C4 interoperability protocol and underlying fabrics. The product describes AtomOS as a free, RHEL-compatible KVM hypervisor with GPU passthrough, autonomous clustering, and unlimited VMs. Desktop installers are available for Linux, macOS, and Windows 10/11. Start costs €199 a month, billed annually, for up to 7 active connections; Grow costs €399 a month, billed annually, for up to 15. A 7-day trial is listed.
